3 Application filed January eafitb,"@Sri al Kc. i2a4f2'7'fi- This invention relates to well strainers and particularly to certain improvements'in the well strainer shown in my Patent No.

1,634,547 granted July 5, 1927.

The general object of the present invention is to cheapen'the cost ofcconstruction-ofth s groove being connected to the-interior the well strainer shown in my prior, patent without, however, aifectingin any waythe efiectiveness of the well strainer and a fur-' 1o ther object is to provide a well strainerof this character wherein the tubular body or pipe forming the body of the strainer need not be very deeply grooved or in some in stances need not be grooved at all, thuspreventing the pipe from being unduly weakened and, therefore, rendering it liable to break when the strainer is driv-eninto the ground.

A further object is to provide a construetion of this character wherein'the fluid en-' tering thestrainer is subjected to a plurality of strainingoperations;

Other objects will appear in the course of the following description.

panying drawings, wherein I j Figure, 1 is a fragmentary-elevation of a well strainer constructed in accordance with" my invention; V I v c Figure 2is a fragmentary elevation of a slightly modified form of strainer; a V

Figure 3 is an enlarged vertical sectional view of one wall of the pipe andthe strip applied thereto constructed in accordance p with one form of my invention; Figure 4 is a section on th line 4-4 of Figure 3; i

'Figure '5 is a vertical section like Figure I 3, butshowing another embodiment of my invention;

Figure 6 is a like view to Figures 5-and 3,

but showing still another embodiment of my invention. r

Referring to Figurefl, the strainer ele- 10, as for instance, a length of pipe which may-be provided at its lowerend. with a pointed element whereby it may be driven into the ground as, illustrated in my prior patent, this pipe being preferably grooved as My invention is illustrated in the accomment consists generally of a tubular body at [11 :to" receive ca metallic strip or tape des ign-ated this tape-being. provided with a plurality transverse slots 13. As illu'se trated' in Figure ,3, the wall of the pipe 10 is fermed-vvith a groovel i which is disposed immediately-beneath the ribbon or strip 1'2,

of the pipe by 'a lpl'urality of relatively small perforations 1'5: In Figure 1, the metallic ribbon'12, is illustrated as extending; spirally around; the pipe 1 and the groove 11 is spirally 'cut around, the pipe, but I ."do' not and while-preferably these grooves" M 01' 14*Ffare' formed in the pijpe 10 itself, I donot wish t'o be l-imited to 'this as itis' entirely possible to form the grooves, as" for instance a the grooves 16, asshown in Figure 6 in the-f ribbon;

There maybe one or more of these grooves in the ribbon or metallic strip 12. In either 13 in the ribbonand pass around the pipe and enter the interior of the pipe through the perforations'lfi 1 a x V Y It will bejunderstood that I do not wish to be limited to the'use of'the ribbonarranged, in ,aspiral around the pipe or disposed in a special groove .11, though this I regard as til .1 case, there is formed a duct extending oircumferentially around the pipe orspirally around the pipe or longitudinally along the, ipe and' water will enter through the slits;

the preferable way of forming the strainer.

It will beseen that with'this construction, the ribbon is held between the walls of the recess 11 sothat when the pipe is driven, the ribbon ca'nnot get out of position. It will [further be seen that by thisconstruction, a;

clogging of anyone of the slits 13 or a clog-.

ging of thegrooves 14 or 1 1 at any particular point will not vitally affect the strainer nor the clogging of any of the perforations 15, as if one or more of the perforations 15 are clogged, the water will simply flow along the duct formed by the grooves 14 or 14 until it finds a perforation which is clear. At the same time the water is submitted to two straining actions in passing through the slots 13 and through the perforations 15. The metallic ribbon or strip 12 may be disposed inthe recess 11 either loosely, the ends of the strip being held as by weldin or soldering or the strip might be sol ered or welded along its entire length. Preferably, it will be loosely disposed so that watermay enter around the edges 11 as well as through .the slots 13.

While I have illustrated the groove 14 as being disposed on the middle line of the strip 12, it is obvious that it might be disposed in other positions with relation to the strip and yet accomplish the desired result.

I claim I 1. A well strainer comprising a tubular bod having a spiral recess extending along the body along its outer surface, the bottom of the recess being formed with a groove and there being perforations extending from the bottom of the groove into the interior of the body and a metallic ribbon-like strip disposed in said recess, the strip being transversely slotted throughout its length.

2, In a well strainer, a tubular body having a recess formed therein, a metallic strip disposed in the recess, the strip'and the body having confronting faces, one of said faces being formed with a groove extending longitudinally of the strip, the body having perforations opening into said groove and the strip being formed with slits transverse to the strip and openinginto said groove.

In testimony whereof I hereunto afiix my signature. A r JOHN M. LOSACK.
